Question

What shapes are formed by cross sections parallel to the base of a square pyramid? A.Similar triangles B.Similar squares C.Triangles of the same size D.Squares of the same size

Answer 1

B. Similar squares

Explanation:

The cross sections parallel to the base of a square pyramid, will form a square which will be similar to the base of the pyramid.

Also, if we consider a rectangular pyramid, the cross sections parallel to the base of the rectangular pyramid, will form a rectangle which will be similar to the base of the pyramid.

Thus, the paralel cross section to the base of any pyramid will form a similar shape of its base.
